目的:探讨亚低温干预对急性辐射损伤小鼠的保护效果。方法40只雄性BALB/c小鼠随机分为4组,受照组均接受6 Gy γ射线单次全身照射,(亚低温+照射)组在照射前给予亚低温干预(28℃~30℃),(照射+亚低温)组照射后给予亚低温干预,动态观察各组小鼠体温、体重、外周血白细胞,照后28天解剖观察脏器与骨髓恢复情况。结果与单纯照射组相比,(亚低温+照射)组外周血白细胞数恢复时间提前1周,胸腺重量和系数增大,且差异显著;(照射+亚低温)组外周血白细胞数恢复时间提前4天。结论亚低温对6 Gy单次全身照射小鼠有一定的辐射损伤保护作用。
目的:探討亞低溫榦預對急性輻射損傷小鼠的保護效果。方法40隻雄性BALB/c小鼠隨機分為4組,受照組均接受6 Gy γ射線單次全身照射,(亞低溫+照射)組在照射前給予亞低溫榦預(28℃~30℃),(照射+亞低溫)組照射後給予亞低溫榦預,動態觀察各組小鼠體溫、體重、外週血白細胞,照後28天解剖觀察髒器與骨髓恢複情況。結果與單純照射組相比,(亞低溫+照射)組外週血白細胞數恢複時間提前1週,胸腺重量和繫數增大,且差異顯著;(照射+亞低溫)組外週血白細胞數恢複時間提前4天。結論亞低溫對6 Gy單次全身照射小鼠有一定的輻射損傷保護作用。

This paper is to investigate the effect of mild hypothermia on acute radiation syndrome in mice . Forty male BALB/c mice were randomly are divided into 4 groups .The mice were exposed to gamma ray at 6 . 0 Gy ,0 .92 Gy/min ,the mice in mild hypothermia+radiation group were received mild hypothermia treatment before irradiation and radiation + mild hypothermia group after irradiation . The descend range of pripheral blood leukocyte number in mild hypothermia + radiation group was 1 week in advance to restore ;Thymus weight and coefficient increased ,the ratio of PCE/(PCE+NCE ) was lower than radiation group .The descend range of pripheral blood leukocyte number in radiation +mild hypothermia group was lower than radiation group on the first day after irradiation ,and 4 days in advance to restore .The descend range of pripheral blood leuko-cyte number in mice treated by mild hypothermia either before or after irradiation decreased lower in early time after irradiation and recovery earlier ,Mild hypothermia had some protective effect on mice radiated at 6 Gy .
